corporation of Maryland Application July 10, 1950, Serial No. 172,966

This invention relates to hulling equipment for legumous vegetables andmore particularly to the class of machines that separates hulls frombeans or peas. to ,discardthe first and selectively deliver the. last topredetermined locations for packing or This invention is similar ingeneral structure.

and principle to that made the subject matter of the patent application,Serial Number 100,153, filed in the United States Patent Oflice, butconstructed with improvements that add certain practical features notattained in previous machines of this nature.

One of the objects of this invention is to provide a new and improvedhulling machine for beans and peas,'that will have its sorting screensmade readily removable and otherwise less difficult to handle formaintenance work.

Another object of the invention is to provide a new and improved hullingmachine for beans, peas and the like, that will be capable of handlingthe material, to be processed therein, without stressing its'sortingscreens excessively or causing uneven rotation or wobbling.

A further object of the invention is to provide a new and improvedhulling machine that will be designed to prevent packing of the hulls instructural corners of the device during its use.

An additional object of this invention is to provide a new and improvedhulling machine for beans, peas and the like that will process thevegetables eifectively, in a smooth and continuous manner.

Other objects of the invention will become apparent as the invention ismore fully described.

For a better understanding of the invention and the objects thereof,reference is made to the accompanying drawings, which in conjunctionwith the following description, illustrate a particular form by way ofexample, while the claims emphasize the scope of the invention.

In the drawings:

Figure l is a perspective view of a hulling machine for peas in the pod,embodying this invention, its housing being partly broken away to showits interior construction; 4

' ner support, screens, channels and U member.

Similar reference characters refer to the same parts throughout thedrawings.

In the construction indicated, a rotating screen z'claims. (01.13040).

IU of boxed-in form and hexagonal cross-section is used for whole peasin their pods to be placed therein to be hulled. It has an entrance orfeed spider II at one end, including an orifice [2' through which thepeas in their pods are introduced. This spider II has a centrallylocated sleeve l3 arranged externallyto act as a bearing to revolve inan outer bearing l4 and internally to receive a rotating shaft I5, Thespider II is preferably dished inwardly to assist in feeding the podsinto the screen to be hulled.

- At the opposite end of the screen 10, a dis charge spider 2| isattached, but is left partly open the panels and are passed to asuitable conveyor underneath to be taken away as required or necessaryfromtime to time. The panels Hare provided with edges 19 bent angularlyupwardly.

The screen structurehas six longitudinal runners 20 extending from thespider I l to the spider 2| and fastened at the ends by bolts 22thereto. The runners 20 are preferably made of pipe with holes 52therein, and form a rigid frame structure for the screen. They supportthe panels I! with their edges [9 sticking upwardly, when channels 23having holes 53 therein are laid longitudinally thereon and secured bythe bolts 24 passing through them. The channels 23 are positioned on theoutside of the screen. An additional U-member 25 is placed on theunderside of the runner structure to contact each pipe 20. It is held bythe same bolts 24 and wing nuts 54 and clamps the parts in between. Therunner structure forms the framework of the screen, and with theperforated panels I! thereon, makes a very substantial screen, ofhexagonal contour. The shaft l5 runs axially through the interior spaceof the screen and is held in the internal bearing 26 in the sleeve I3 atone end, and in a similar bearing 21 in a sleeve 28 extending similarlyfrom the discharge spider 2!. Six paddles 46, 41, 48, 49, and 5| aremounted on the shaft and preferably spaced degrees apart in a helicalmanner as noted in Figures 2 and 3. They are so mounted that they tendto drive the vegetable material in the screen from the feed orifice l2towards the discharge opening in the spider 2|.

The paddles are built in the form of spokes and with blades 29predeterminedly pitched and in T-form therefrom and designed to open thehulls that supports the screen and the mechanism that operates it. Theframe is provided with legs 36 that support the machine off the floor.The screen is rotated through the use of sprocket gear 31 mounted on itsleeve28 and driven by another sprocket gear 38 actuated by a.transmission chain 40 driven by a'motor 39. The

shaft I5 is also rotated by the motor 39 through the use of sprocketgears 4| and 55, andtrans- 1. In a hulling machine, a generallypolygonal screen, said screen including removable sections, and meansfor securing the adjoining ends of said sections, said means comprisingturned up extensions at the ends of the screen sections, a set oflongitudinal channels encompassing the turned-up extensions, pipesextending from end to end-of the screen adjacent and beneath theturned-up extensions, a second set of longitudinal channels encompassingthe said pipes, both sets of channels having their sides aligned in thesame direction, bolts extending through the webs of both sets ofchannels and through said pipes to secure these elements together.

2. A hulling machine comprising a polygonal screen, said screenincluding removable sections,

each of said sections having turned-up extenmission chain 56. The shaftand paddles are rotated about 10 times faster than the screen, but theypreferably run in the same direction.

The operation of the device does not seem to require further detailing.The features most conspicuously noticeable in the machine, include thosethat give the screen a tumbling action'by reason of the hexagonalshape;the non-clogging and lifting action performed by theextending- U-membersthe propelling action of r the paddles, the convenient efiective andexpeditious arrangement for attaching or detaching the screen plates,the covering of all moving parts to make it safe,-an d the neat, compactand attractive design that it provides. A supply storage 43-is connectedto the housing 51 and througha suitable duct pours the peas into thescreen through the 'orifice 12 as required. While but one general formof the invention is shown in the drawings and described in thespecifications, it is not desired to limit this application forpatent tothis particular form, as it is appreciated that other forms ofconstruction could be made that would use the same principles and comewithin the scope of the ap pended claims.

Havin thus described the invention, what is claimed is:

sions, means for assembling adjoining sections comprising longitudinalchannels enclosing the turned-up extensions, runners extending from endto end of the screen adjacent and beneath the turned-up extensions, asecond set of longitudinal channels encompassing the said runners, bothsets of channels "having their sides aligned, bolts extending throughthe webs of both sets of channels and through the runner to secure theseelements together, a shaft running longitudinally through the screen, aplurality of paddles helically mounted on said shaft for propelling andopening of the pods being hulled and means for rotating said shaft.
